' This invention pei'teine -toimprovements in oil cups. t is among the 'objects of the invention to provide e cup through which lubricant-mcy be lueheci umier'pressure imm i eur-oil gun en@ which, when seid pressure is V.oveds 'e'iil mcrfefsicwy feed lubricant to the part to be lubricated.

in the drawings, which ebow e. preferred form of one embofliment. of my invention:

Figure i is o side elevation of e. lubricant cup provided with e. quick detachable con.- luection;

Fig. 3. is a. section on the line 3-3 cit lig. 2f, being partly in elevation; enti i is s section en the Line 4.-4 of Fig. fi, being partij; iu elevation.

liefcrring to the drawings aud to the pre- 20 errecl -crm o my invention selected for illustrative purposes, l have ebowu e cup in cludiig a body 5 engaging c. bottom 'Dertien t3 promde with e, valve 'i' nterposecf in the ci tbe' iubricazit tc the passage 8 coni muiiiceting with the part to be lubricated. Above the metal pertion of tbe valve 'L 'time provid-eri e porous washer 9 which may Je te permit seepage ci the iubrcant therethroiig when the velue ie closed.

Vheu the pressure on 'the lubricant supplied through the nipple El is removed, the vaive 7 will dose, leaving tbe cup 5 filled with the ubricaut, which Wiil tlien seep slowly 5%' through thefelt 9 and thence be vslowly ie@ by gravity through the port 8 to the peri; to be iubricateci.

The valve i' may be formed to iit the iuterior of e cylindrical recess in 'the lower portion 6 of the cup, and also be guided by an upwardly extending stem l2 movable in guided relationA to the head (i, es best shown in 1F ig, 3. `Wl1ere this guided. construction isAused, the initial passage of 'the lubricant may be through the Borte 13 and recesses lll in the periphery cf tue valve proper 7.

Vhile l have eliowu and described .c preferred embodiment of my invention, it will be understood that l have done so' for purposes of clerilieetion and not forv purpesefs limitation. My' invention best deiued in 'the following cia-imei.,
